Yes, but Banggood traditionally been a reliable source for Samsung 30Q’s, so it is an interesting and unfortunate development to see them delivering fakes. I don’t trust the company any further than I can throw them, but there have been situations in which they became a reliable source for certain products. Considering how difficult and expensive it is to buy and ship authentic li-ion cells, it’s a rather large blow to find that Banggood’s 30Q’s are not trustworthy.
They often offer four 30Q’s for ~$20 with minimal shipping charges to the U.S., so they became a popular source for these “universal” cells. There are stores that have better sales on genuine 30Q’s, but shipping (understandably) offsets even lowest best per-cell prices.
I do agree, however, that this trend fits with Banggood’s not-so-hard-earned reputation for general badness :person_facepalming: .
I bought one of their BLF A6 kits with included 30Q last November and I believe that cell is genuine and tests right around 3000mAh. It looks like Barkuti’s reference images. The L0I7 date code makes sense, though not super-fresh: I (2018), 7 (July).
I don’t have any, but I think that cells made in 2019 would have a xxJn in the top-most code on the metal can, where n is the month (i.e. hexadecimal 1-C). As I understand this, Barkuti’s cell appears to made in March, 2017.
